The Prime Minister and Deputy Prime Minister have offered their support to
Labour leader Ed Miliband after the Daily Mail stood by a profile describing
his father as "the man who hated Britain".

Mr Miliband wrote a letter in response, which was published in the newspaper, claiming the "absurd" profile was based on a diary entry written by his adolescent father, who fled Belgium aged 16 to escape the Nazis.

The newspaper subsequently reprinted the essay on Ralph Miliband alongside his son's piece, together with a leader column attacking the "tetchy and menacing" response from the leader of the Opposition.

David Cameron admitted he had not read the orginal article nor Mr Miliband's response, but said: "All I know is that if anyone had a go at my father, I would want to respond very vigorously.

"There's not a day goes by that you don't think about your dad and all that he meant to you, so I completely understand why Ed would want to get his own point of view across."

Nick Clegg tweeted: "I support @Ed-Miliband defending his dad. Politics should be about playing the ball, not the man, certainly not the man's family."

In the essay, first printed in Saturday's edition of the Daily Mail, Geoffrey Levy examined the political beliefs of Marxist academic Ralph and how that influenced his two sons.

It questioned what Ralph Miliband, who died in 1994, "really" believed in, adding "the answer should disturb everyone who loves this country".

The Daily Mail had quoted the 17-year-old Ralph writing that the Englishman is a "rabid nationalist" and "you sometimes want them almost to lose (the war) to show them how things are".

In his reponse the Labour leader said fierce debate about politics did not justify "character assassination" of his father, who joined the Royal Navy and fought in the Second World War after arriving in Britain.

He also won the backing of his elder brother and former rival David, who tweeted: "My dad loved Britain."

The younger Miliband wrote: "Like most refugees, the security of our country was really important to him. And like some refugees, he owed his life to it. So my Dad loved Britain, he served Britain, and he taught both David and me to do the same."

Mr Miliband said he accepted politicians needed to be held to account but what appeared in the Daily Mail on Saturday "was of a different order altogether".

He said: "I know they say 'you can't libel the dead' but you can smear them.

"Fierce debate about politics does not justify character assassination of my father, questioning the patriotism of a man who risked his life for our country in the Second World War or publishing a picture of his gravestone with a tasteless pun about him being a 'grave socialist'.

"The Daily Mail sometimes claims it stands for the best of British values of decency.

"But something has really gone wrong when it attacks the family of a politician - any politician - in this way. It would be true of an attack on the father of David Cameron, Nick Clegg, or mine.

"There was a time when politicians stayed silent if this kind of thing happened, in the hope that it wouldn't happen again.

"And fear that if they spoke out, it would make things worse. I will not do that. The stakes are too high for our country for politics to be conducted in this way. We owe it to Britain to have a debate which reflects the values of how we want the country run."

Mr Miliband described how his father arrived in Britain as a Jewish refugee, then joined the Royal Navy at 20 and fought for his adopted country as part of the D-Day landings.

On why his father joined the navy, Mr Miliband added: "He did so because he was determined to be part of the fight against the Nazis and to help his family hidden in Belgium. He was fighting for Britain."

In its examination of Ralph Miliband, the Daily Mail article stated: "As for the country that gave him and his family protection, the 17-year-old wrote in his diary: 'The Englishman is a rabid nationalist. They are perhaps the most nationalist people in the world . . . you sometimes want them almost to lose (the war) to show them how things are. They have the greatest contempt for the Continent . . . To lose their empire would be the worst possible humiliation'.

"This adolescent distaste for the British character certainly didn't stop him availing himself of the fine education that was on offer in this country, or spending the rest of his life here."

The newspaper's comment piece printed alongside Mr Miliband's response said: "We stand by every word we published on Saturday."

It added: "Yes, as his son argues, Mr Miliband Snr may have felt gratitude for the security, freedom and comfort he enjoyed in Britain.

"But what is blindingly clear from everything that he wrote throughout his life is that he had nothing but hatred for the values, traditions and institutions - including our great schools, the Church, the Army and even the Sunday papers - that made Britain the safe and free nation in which he and his family flourished."

The paper also attacked Mr Miliband for his support of tougher press regulation in response to the Leveson Inquiry: "If he crushes the freedom of the press, no doubt his father will be proud of him from beyond the grave, where he lies 12 yards from the remains of Karl Marx.

"But he will have driven a hammer and sickle through the heart of the nation so many of us genuinely love."

A senior party source said: "Ed Miliband wrote his right to reply article because he wanted to state clearly that his father loved Britain.

"He wanted the Daily Mail to treat his late father's reputation fairly. Rather than acknowledge it has smeared his father, tonight the newspaper has repeated its original claim. This simply diminishes the Daily Mail further.

"It will be for people to judge whether this newspaper's treatment of a World War Two veteran, Jewish refugee from the Nazis and distinguished academic reflects the values and decency we should all expect in our political debate."
